Forest Reverb Model

For your auditory pleasure, Travis Wiens and Nutaksas Research are pleased to announce the release of a Forest Reverberation Modeller. This package of Matlab functions allows you to simulate the impulse response of an arbitrary forest of any number of trees of any size at any location, as well as source and listener lcoations.
Based on Morse's theory, each tree is treated as an acoustically hard cylinder and the effect of each path from source to receiver via any number of trees is calculated. The maximum number of scatterings may be limited to cut down on excessive calculation times.
The idea was based on Kyle Spratt's Treeverb proposal, although it was developed independently and gives different results.
Download the code from Matlab Central File Exchange, and feel free to check out the other files available. Watch this space for a more technical description.
